Volkswagen Golf Service & Repair Manual: Wear in middle of tyre
This wear pattern is found on the driven wheels of
high-performance vehicles that are frequently driven long
distances at high speeds. |
At high speeds, centrifugal forces cause the tyre diameter
to increase more in the middle of the tread than it does at the
shoulder. This causes drive forces to be transferred to the road
surface from the centre section of the tread. This is reflected
in the wear pattern. |
Effects of this kind can be especially pronounced on wide
tyres. |
It is not possible to counter this wear pattern by reducing
the tyre pressure. |
WARNING
For safety reasons, the tyre pressure must not under
any circumstances be reduced below the specified tyre
pressure. |
|
A more or less even tread wear pattern can be achieved by
interchanging the tyres on the driven wheels and non-driven
wheels in good time. |
|
|
|
The typical tread wear pattern of tyres run on the driven
wheels of a high-performance vehicle. |
The increased wear in the centre section of the tread
results from the extra loading associated with centrifugal
forces within the tyre and the transmission of drive forces. |
